Problem Solved 
Hi. I have many aircraft including the black square analog. I am facing serious issues with the 750nxi that made me just delete it.
The GPS does not work on most aircraft and conflicts with gnx 430/530 and in some aircraft the Vloc1/GPS flickers. In some aircraft, two units do not sync .... I have also PMS 750 which is working well.
I tried removing the PMS 750 but still, the nxi does not work well. My conclusion is the NXi 750 is just buggy unless there is a clear fix.
Regards.
Another simple point. Why hardware acceleration is still recommended to be turned off knowing that you can not use DLSS3. yes the NXI delivers very poor FPS impacts on all aircraft also. the 750 NXI is not recommended and I believe the Garmin code is not ready to work with MSFS. It can deliver nice demos only.
